I'm sure for the sake of convenience that this works, however more and more are car sharing or getting to the ground under their own steam. Several probably already have their own travel passes (student / OAP). it would be interesting to see an exact calculation.
How are the figures calculated to pay the transport companies. Coaches I presume are easy, No. of coaches x cost.
However with trains and local buses how do you put a cost on it, all we do is wave a card or ticket and jump on. Could the club / transport companies build in an oyster card type...
